Matthew D. Rocklage and team examined whether consumer ratings of movies can predict box office success. The team considered both numeric star ratings and written reviews in their research. To analyze the written reviews, the team measured the emotionality—the degree to which a written review expresses an emotional reaction—of user reviews on a movie rating website, assigning each review an emotionality score. After reviewing this research, a student argues that the emotionality of movie reviews is unrelated to a movie’s success at the box office.
Which finding, if true, would most directly weaken the student’s conclusion?

(Choice C) The movies that were most successful at the box office tended to have high average star ratings.
C
The movies that were most successful at the box office tended to have high average star ratings.
(Choice D) Movies that had the highest average emotionality scores received the lowest average star ratings on the movie rating website.
D
Movies that had the highest average emotionality scores received the lowest average star ratings on the movie rating website.
Choice A) The average emotionality score of a movie’s reviews was a positive predictor of that movie’s box office earnings.
This finding would directly weaken the student's conclusion by showing a correlation between emotionality of reviews and box office success. If movies with higher emotionality scores tended to have higher box office earnings, then it suggests that there is a relationship between emotional reviews and movie success.
